To all whom it may concem."

Be it knownthat JAMES P. Hoorna, a citizen of the United States, residing at Ruxton,

.in the county of Baltimore and State of Maryland, has invented certain new and useful Improvements in Apparatus for Forming Threads of Viscous Material, of which the following is a specification.

This invention relates to an improved mechanism for formin viscous threads; partially solidifying t e same; depositing the partially solidified thread in the form of a skein in a suitable receptacle and expelling, by centrifugal force, the excess moisture and thereby drying and further hardening the thread.

The invention Y further consists of imroved mechanisms and devices for carrymg out the several steps above enumerated.

With these, and other obects in view, the invention is illustrated in t e accompanying wherein,- Fig. 1. shows the improved mechanismin .front elevation.

Fig. 2. illustrates the same in sectional side elevation.

Fig. 3. shows an enlarged longitudinal section through thespinneret.

Fig. 4. illustrates a cross-sectional detail through the spinneret,the section being taken on the line 4-4 of Fig. 3.

Fig. 5. shows a plan view of the boltcarrying bar and a cross-section through the guide rods and operating rod. L

Fig. 6, illustrates an enlarged sectional detail through one of the centrifugal cups and the means forrevolving the same together with the means for locking the cup mechanism in the rotating position, and

Fig. 7. shows a plan view of the cup carrier and the driving mechanism.

' of a beveled joint shown at 18, in Fig- 3 and a retaining screw 19, holds the parts to ther in such manner as to permit the j s mneret to be rocked without interrupting t econnection. The spinneret which is best seen in Figs.

.head 20, at the inlet-en sage 21 and a side passage-22, through w 'ch 3 and 4, consists of a cglindler. 17, having a wit a central asway through the spinneret and its head for a purpose that will presently be explained.

Beneath the spinneret there isprovided a receptacle 27 which is sustained by the supporting members 14, and during the operation of the machine, the discharge-end of the spmneret dips into a setting solution 28, that is contained in said receptacle so that the strands of viscous material discharged throu h the passages 25 of the nozzle will be en jected to the action of the setting solution, as and for purposes well known in the art. C

It is my pellergiose to provide means whereby I may a strand of thread in such manner that the strands of viscous material ejected through the nozzle 24, may cover said thread and be reinforced thereby. To this end I provide a thread carrier 29, from which a thread 30 is run to and through the After being subjected to the action of the solution, the thread is then passed over suitable guide devices 32, and around a roller 33, which latter directs the thread downwardl to a mechanism which will now be explained: The under side of su porting member 12 and the under side of t e front member 13, carry supporting brackets 34, which latter sustain two spaced-apart vertical guide rods 35. These rods-are rigid and have no movement and simply serve as guides for a crosshead structure 36, which latter has a central bearing or supporting arm 37, that carries a depending tube 38 with a funnel 39 at its upper end for a purpose that will also presently be explained.

This cross-head 36, tube 38 and funnel 39 are all designed to have a somewhat slow but vertically recipr ating movement whereby to feed the thread into i W 6%therein wheieby the same may be broken Tigidly held therein'py means ot set serew rocked, and link 42,will cause the cross-tate 36 to reciprocate verticall on the guide-rods 35, thereby imparting a ike vertical movement to the tube 38.

It is to be noted that lever 40, has a joint at the joint and the forward end thereof moved upwardly without regard to the arm 43. This construction is provided to enable the cross-head and guide tube 38 to be elevated without stoppmg the cam-shalt, for a a pu out that will presently be explained. e lower ends of the vertical guide rods 35, also serve as guides for ahorizontal latch or bolt-carrymglbar 47 whose under side earries a verti and whose rear side has a perforated lag 49. An operating rod 50 has its lower end projecting down through the lug 49, and is 51. This operating rod 50., extends vertically and the rear 0 the cross-head 36,'so that said cross-head may make its vertical reciprocations without moving said operatingrqd. The upper end of the operating .rod 50 is provided with a stop nut or equivalent device 53, so that when the cross-head 36, is elevated by hand, for the purpose of raising the lower end of tube 38, said cross-head eye 52, will strike the stop nut 55'} raise the rod 50, and lift the bar 47 and bolt 48. The reason for this will hereinafter be more fully ex lained.

elow vthecross-head 36 and receptacle 27, there is provided a vertical pedestal 54 which is mounted on the supporting member 10 and a vertical shaft 55, extends up through this pedestal and carries a' gear 56 on its upper end which latter revolvesin a horizontal plane. The axis of this gear 56 is not central with the vertical axis of the pedestal but is eccentric with respect there to, as can be clearly seen in Fig. 7 of the drawing. A horizontal bar 57 is mounted on the upper end of the pedestal immediately beneath the gear 56 and this bar extends at'opposite 4 sides from said pedestal-end and carries a rotatable inverted cup or housing 58, at each end thereof. Each cup has a hollow sleeve 59 projecting upwardly therefrom which passes through a bearing structure on the arm that is constructed to "facilitate its roy pro ecting holtfi passes freely through an eye 52 on through a drain pipe 67.

tation, and each sleeve is rotatable through a pinion 60, although in the present structure but one cup and one pinion is to be revolved at a time.

Two operating handles 6Yare provided in the bar 57 which extend at right an les thereto whereby the bar may be rotate on the pedestal.

By reference to Figs..2 and 6 it will be noted that the bar 57 and pedestal 54 are so positioned with respect to the vertical axis of thedepenciing tube 68, that the bar may be swung so that one cup-sleeve 59 at a time may be positioned directly beneath the depending tube in order that the latter may e projected down therethrough and into the interioroi the inverted cup58 beneath it.

It will also be noted, by reference to Fig. 7, that when the bar is so'turned as to permit the lower end of the yertical tube 38 to enter the cup-sleeve 59, that at that position the gear 56, will mesh with the pinion 60 of said cup-sleeve and cause the latter and its cup to be revolved.

When the cup-sleeve and tube are in register and the tube is lowered so its lower end williprojectintorthe -cup the. lowering of the tube through the downward movement of the cross-head 36,'wil1 cause the bolt 48, to be lowered and when so lowered, this helt'enterse pertoratien in the end oi the bar 57 whereby to lock the same against accidental displacement.

From the foregoin explanation it is to be understood that as t e tube 38 reciprocates verticallv. during the formation of the thread, its lower end, from which the thread is ejected, will move up and down in the inverted cup while the latter is revolved. 'lhese movements cause the thread to be thrown laterally against the circular sides of the cup and laid there in a skein-like form. The vertical movement ofthe tube and the rotation of the cup also serveto impart a slight tension and twist on the thread. Each cup is provided with a detachable bottom 63 and bolts 64 which retain the same in place, and upon removal of the bottom the skein will drop from the cup.

When the thread, leaves the end of tube 38, it is wet withthe setting solution and during rotation of the cup this moisture leaks from the bottom and. is thrown laterally by centrifugal force. I therefore provide a shield device. 65, with a gutter or trough 66 at its lower edge whereby to catch this thrown moisture and carry it off Wheii a'cup has been filledwith thread, the operator may raise the cross-head 36 in the guide rods 35,the lever 40, during this movement simply breaking on the pivoted.

joint therein and this upward movement of said cross-head raises the tube 38, entirely from the .cupesleeve. During the last portion of this upward movement, the rod 50,

is lifted and bar 47 will therefore be raised so as to lift the bolt 48 from engagement 56, but moves the pinion of the empty cup into mesh therewith. The tube and lock may then be lowered and the operation continued.

Having described my invention, I claim,.

1. In a device for receiving threads of viscous material the combination with an inverted cup, of means for pendantlySustaining said cup, means for rapidly revolving said cup and meansfor delivering the thread at the axis of said inverted cup.

2. In a device for receiving threads of viscous material the combination with a pedestal of a vertical shaft through the edestal, a gear on the upper end of said sha the axis of the gear beingeccentric with respect to the axis of the pedestal, means mounted to turn from the center of the pedestal and extending to opposite sides of said pedestal-center, an inverted cup carried by said latter means on opposite sides of the axis of the pedestal, means attached to each cup by which the latter may be driven when at one side only of the eccentrically mounted gear and means for delivering the thread at the axis of the driven cup.

In testimony whereof I aifix m si ature.
